Patent GB-1891-8142
An elongated metal balloon is given the necessary ascentional force by creating a more or less complete vacuum within same. The balloon, which is constructed of thin steel plates, is strengthened by an internal framework, and the inventor considers 738 ft. long and 144 ft. diameter to be suitable dimensions.
Aëroplanes, inclined downwards at an angle of about 45°, project from either side of the balloon.
A car is suspended below the balloon and is adjustable longitudinally, thus regulating the angle of the apparatus.
An exhaust fan is employed to propel the machine by the impact of a current of air, and by adjusting the outlet the direction of propulsion may be controlled at will.
This invention is very similar to No. 316, A.D. 1887, by the same inventor.
